Hello,
Using ALSA modules shipped with Linux 2.6.20, I find that with a HP
dc7600 workstation I need to load snd-hda-intel with model=basic or
model=hp or there is no sound. Alsamixer indicates Chip: Realtek ALC260.
00:1b.0 0403: 8086:27d8 (rev 01)
Subsystem: 103c:3010
This system is in the latest driver, 1.0.14rc3.Try this patch and report back if it works.Same with a Lenovo M55 8811, except I seem to need model=laptop. alsamixer indicates Chip: Analog Devices AD1986A. 00:1b.0 0403: 8086:284b (rev 02) Subsystem: 17aa:1011
You can get alsa-driver-1.0.14rc3.tar.bz2 from ftp://ftp.alsa-project.org/pub/testing/alsa-driver-1.0.14rc3.tar.bz2
If this patch works, then here's my summary in advance:
Summary: Add support for Lenovo M55 Laptop
This patch adds support for the Lenovo M55 Laptop to the HDA drivers.
